CPI_type is stated in the PlayList( ). There are EP_type and EP_map type in CPI_type. If the position of an I-picture can be known by analysis, EP_map type is used, whereas, if the position of an I-picture cannot be known by analysis, EP_map type is used. By so doing, AV stream data recorded subject to analysis of the I-picture and AV stream data recorded without analyzing the I-picture position can be supervised in common.
